Abstract

1. Способ передачи программных кодов в программную память прибора управления, в частности, автомобиля, включающий в себя следующие операции:а) подключение интерфейса прибора управления к программирующему устройству с программными кодами;б) приведение всех ячеек программной памяти прибора управления к стандартному значению;в) упаковка программного кода программирующего устройства способом упаковки данных без потерь;г) передача упакованного программного кода на прибор управления;д) распаковка принятого программного кода в приборе управления;е) хранение распакованного программного кода в программной памяти прибора управления.2. Способ по п.1, отличающийся тем, что во все, не используемые ячейки программной памяти прибора управления записан недействительный программный код.3. Способ по п.1, отличающийся тем, что стандартное значение является недействительным программным кодом.4. Способ по п.2 или 3, отличающийся тем, что недействительный программный код передается с программирующего устройства на прибор управления.5. Способ по п.1, отличающийся тем, что с программирующего устройства последовательно передаются на прибор управления только действительные программные коды, в то время как значение недействительного программного кода передается не более одного раза.6. Способ по п.1, отличающийся тем, что упаковка и распаковка программных кодов проводятся после кодирования по Хаффману.1. A method of transferring program codes to the program memory of a control device, in particular, a car, including the following operations: a) connecting the interface of the control device to a programming device with program codes; b) bringing all cells of the program memory of the control device to a standard value; c ) packing the program code of the programming device in a lossless data packing method; d) transferring the packed program code to the control device; e) unpacking the received program code in the control device; f) storing the unpacked program code in the program memory of the control device. 2. The method according to claim 1, characterized in that an invalid program code is written into all unused program memory cells of the control device. The method of claim 1, wherein the standard value is an invalid program code. The method according to claim 2 or 3, characterized in that the invalid program code is transmitted from the programming device to the control device. The method according to claim 1, characterized in that only valid program codes are sequentially transmitted from the programming device to the control device, while the value of the invalid program code is transmitted no more than once. The method according to claim 1, characterized in that the packaging and unpacking of the program codes are carried out after Huffman coding.
